st: Add new observations in the dataset
Date

Dear Statalists,
I have a panel dataset that looks as follows:
year city x1
2008 Ancona 5
2008 Bari 1
2009 Ancona 8
2009 Bari 3
2010 Ancona 9
2010 Bari 8
I would like to add for each year a new observation "Italy" whose x1'
values are the sum of the x1's values of Italian cities:
year city x1
2008 Ancona 5
2008 Bari 1
2008 ITALY 6
2009 Ancona 8
2009 Bari 3
2009 ITALY 11
2010 Ancona 9
2010 Bari 8
2010 ITALY 17
Is there a direct way to obtain this result or I have to use collapse,
save the dta with only Italy, and append it to the complete dta?
Thank you fot your time and assistance
Best regards
Alice
